DRY ICE EXPERIEMENTS CLOUD BUBBLES Bubbles are cool, but bubbles filled with fog are even
cooler. Cloud bubbles are what you get when you fill a bubble with a carbon dioxide cloud using a cloud bubble generator. Let’s get started...

DRY ICE EXPERIEMENTS
CLOUD BUBBLES EXPLANATION
Dry ice is frozen carbon dioxide. When you drop pieces
of dry ice into water, you get a wicked-cool combination of carbon dioxide gas and water vapor that bubbles out of the water. The creation of gas inside the two liter bottle quickly becomes too much volume for the two
liter bottle to contain and the dry ice smoke flows over.
?
By capping the two liter bottle with a funnel, the smoke
builds pressure as it is forced into a more confined area. This pressure pushes the smoke through the tube, creating a flow of smoke that fills the bubbles.

Q
What happens when you pop the bubbles? Why doesn’t the bubble pop immediately?
